colregul - removing poles and zeros at infinity

Calling Sequence

[Stmp,Ws]=colregul(Sl,alfa,beta)

Parameters

• Sl,Stmp : syslin lists
• alfa,beta : reals (new pole and zero positions)

Description

computes a prefilter Ws such that Stmp=Sl*Ws is proper and with full rank D matrix.

Poles at infinity of Sl are moved to alfa;

Zeros at infinity of Sl are moved to beta;

Sl is a assumed to be a left invertible linear system (syslin list) in state-space representation with possibly a polynomial D matrix.
